5. Protective Functions
Protective Function (What Is Error Code ?)
• Various protective functions are equipped in the driver. When these are triggered, the
motor will stall due to error, the driver will turn the Servo-Alarm output (ALM) to off (open).
• Error status and their measures
• During the error status, the error code No. will be displayed on the front panel
LED, and you cannot turn Servo-ON.
• You can clear the error status by Alarm clear input(A-CLR) in 120 ms or longer.
• When overload protection is triggered, you can clear it by Alarm clear input(A-
CLR) in 10 sec or longer after the error occurs. You can clear the Overload protec-
tion time characteristics (refer to P.B36, 37) by turning off the control power supply
between L1C and L2C (100 V, 200 V) of the driver.

• You can clear the above error by operating the front panel keys and setup support
softwear “PANATERM”.
• Be sure to clear the alarm during stop after removing the cause of the error and
securing safety.
• The error code No. is displayed in the form of ErrXX.Y (X: main, YY: sub).

Note
History...The error will be stored in the error history.
Can be cleared...To cancel the error, use the alarm clear input (A-CLR).
If the alarm clear input is not effective, turn off power, remove the cause of the
error and then turn on power again.
Immediate stop...Instantaneous controlled stop upon occurrence of an error.
(Setting of “Pr.5.10 Sequence at alarm” is also required.)
